Why is it sufficient to graph this function in the
upper right quadrant only? How far can
Rick drive on 2.5 gallons of gasoline?

  a) see attachment

  b) negative values for miles or gallons are not possible

  c) 45 miles

Step-by-step explanation:

See the attachment for a graph

__

Graphing in the first quadrant is all that is necessary, because the number of gallons and the number of miles cannot be negative.

Use 2.5 for g and evaluate:

  d = 18(2.5) = 45

Rick can drive 45 miles on 2.5 gallons of gas.
